PROBLEM TO BE SOLVED: To provide a method for identifying positional information on a substrate using a simple method, without making complex a part on a substrate for bioassay.;SOLUTION: A reaction region block 3, where a reaction region 2 for providing an interaction field between a substance N for detection and a target substance N' is divided by a specified number of sets, is provided on the substrate 1. A marker M for identification is labeled at the end part of the substance N for detection, existing in each reaction region 2 which is selected in each reaction region block 3. Read information in the excitation/fluorescence wavelength of the marker M for identification is utilized as the identification ID information of each block 3, in the identification method of the reaction block 3.;COPYRIGHT: (C)2005,JPO&NCIPI
